Product features

ZDLY electronic electric small flow regulating valve is a small caliber regulating valve specially developed for small flow regulation. It is small in size, light in weight, high in performance, and used for precise control of small flow. When regulating dirty media, attention should be paid to the problem of small throttling clearance to prevent jamming. Electric small flow regulating valve is suitable for liquid Main flow adjustment of steam and other media, for example, in precision chemical industry and scientific research institutions, it is used for precise micro control of flow and pressure.
